The truth is that nobody knows who invented eyeglasses. At some point in Italy between 1268 and 1289 someone came up with the idea, but the actual inventor remains anonymous. What we do know is that the earliest lenses were made from quartz and were usually set into bone, metal, or leather. As soon as early opticians figured out how to make glass without bubbles and other obstructions, they started making lenses out of glass.
